DESCRIPTION
The M54/74HC352 and M54/74HC353 are high
speed CMOS DUAL 4 CHANNEL MULTIPLEXERS
INVERTING fabricated with silicon gate C2MOS
technology.
Both achieve high speed operation, similar to equi-
valent LSTTL while maintaining the CMOS low
power dissipation. The designer has a choice of
complementary output (HC352) and 3 state output
(HC353). Each of these data (1C0-1C3, 2C0-2C3)
is selected by the two address inputs A and B.
Separate strobe inputs (1G, 2G) are provided for
each of the two four line sections. Taking the strobe
input (1G, 2G) high inhibits the outputs. The output
of HC352 is fixed at logic low level and the output of
HC353 has a high impedance, unconditionally.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
